This calculator is designed to give you a guide on mortgage costs. It also makes certain assumptions to be able to provide calculations over a longer period that will not be reflected in your own mortgage. The actual mortgage you obtain will depend on a number of factors that are specific to your own personal and financial circumstances.

What is a mortgage calculator?

Mortgage calculators are tools you can use to estimate how much you can borrow on a mortgage and other mortgage costs in different scenarios. There are mortgage calculators that estimate mortgage payments, and calculate how much mortgage repayments will increase or decrease if a mortgage rate changes. Others are designed to calculate how much interest you could save by overpaying on your mortgage, and how much faster you could pay off your mortgage as a result. A stamp duty calculator gives you an idea of the amount of stamp duty tax you’ll need to pay the government when buying a home.

Who is a mortgage calculator for?

A mortgage calculator may be used by anyone who has a mortgage or is thinking of taking one out, including:

What information do I need to use a mortgage calculator?

Different mortgage calculators require you to use different information, but some of the details you’ll usually need to have an idea of include:

Do mortgage calculators involve credit checks?

No. Our mortgage calculators are a guide to costs only.

A hard credit check that has the potential to affect your credit score is only carried out by a mortgage lender once you’ve completed a full mortgage application and given permission for it to happen. A soft credit check may be carried out when getting a mortgage in principle, but it won’t impact your credit score.

What will my mortgage repayments be?

Your monthly mortgage repayments will depend on the size of your mortgage, your mortgage rate, and the period of time – or mortgage term – over which you intend to pay off your entire mortgage. You can use our mortgage repayment calculator to help you work out how much your mortgage payments may be. 

How much mortgage can I afford to borrow?

How much you could borrow through a mortgage will depend on several factors. Each lender has its own criteria for calculating how much they may be willing to lend to you. Your income, outgoings,  employment status, credit score and deposit all usually affect the mortgage you can afford. Our mortgage borrowing calculator can give you an idea of the mortgage you may be able to get, but it is just a guide.

How much deposit do I need for a house?

Typically you’ll need a minimum deposit of 5% of a property’s value to get a mortgage. Having a larger deposit, and therefore a lower loan-to-value, usually gives you access to better mortgage rates and deals.

Can a mortgage calculator help to find the best mortgage deals?

Mortgage calculators can help you work out the amount of mortgage you can afford and how different mortgage rates may affect your repayments. However, to find a specific mortgage deal you’ll need to shop around. Speaking to a mortgage adviser is a good way to help you find the best deals for your financial circumstances, or you may be confident to do your own research.

Mortgage calculator FAQs

How much mortgage can I borrow on my salary?

Typically you may be allowed to borrow somewhere between 4 and 5.5 times your salary, but it will depend on the lender and your circumstances. Lenders must make sure you can afford a mortgage, so will also consider factors such as your monthly outgoings, deposit and outstanding debt to calculate the mortgage you can borrow.

What credit score do you need for a mortgage?

The better your credit score the more likely you’ll be offered a mortgage. Having a good credit score suggests to lenders that you’re someone who can generally be relied upon to pay back anything you borrow or owe when you should. 

Should I borrow the maximum mortgage I can get?

The decision is ultimately yours but think carefully whether you need to. Consider whether it would be affordable in practice, or if it may stretch your finances too far. Also think about the future, and the effect that having children, higher interest rates or losing your job could have on your ability to cover your mortgage repayments and live comfortably. Not paying your mortgage can lead to penalties or, eventually, perhaps losing your home to repossession.
